SPECIFICATION forming part of Letters Patent No. 233,026, dated October 5, 1880. Application filed May 26, 1880. (No model.)

To all whom it may concern Be it known that I, PHILO J. RUMSEY, of Marshalltown, in the county of Marshall and State of Iowa, have invented a new and valuable Improvement in Nut-Roasters; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this specilication, and to the letters an d ii gu res of reference marked thereon.

Figure 1 of the drawings is a representation ot' a longitudinal vertical section of my improved roaster, and Fig. 2 is a plan view thereof.

This invention has relation to improvements in means for roasting peanuts, coffee, and other articles requiring roasting; and the invention consists in a machine constructed, arranged, alid operating substantially as hereinafter fully set forth.

In the annexed drawings, the letter A designates a strong rectangular metallic frame having mounted on one end a steam-generator, B, driving a small upright engine, C. The driven shaft of this engine is provided with a ilywheel, D, and a peripherally-grooved concentric pulley, D', around which passes a belt, E, leading to and around a similar pulley, F, on the rca-ster G.

This roaster is composed of an inner and an exterior cylinder, lettered, respectively, H and H', concentric with each other and sepa-rated from each other by an annular space, a.

The cylinder H' is fixed to the frame, while the cylinder H rotates freely in bearin gs in the heads of the cylinder H', and carries on the end of one of its journals the pulley F, aforesaid.

rllhe cylinder H is provided with the sliding door b, and cylinder H with a similar door, c, which, when brought in line with the door b, allows the articles to be roasted to be readily introduced into the rotary cylinder H.

Extending from the cylinder H', across the interval between the same and cylinder H, is

an inclined fixed iiange, d, which acts as a chute to deliver the roasted articles through a door7 e, into a warming-pan, J, arranged beand the engine on frame A,

tween the roaster and provided on its bottom with a water or steam chamber, K.

rIhe peanuts roasted in cylinder warm in the pan J.

L indicates a tank, arranged above the boiler and roaster, and designed to contain a supply ot' gasoline or other inflammable oil. From this tank a main feed-pipe, M, extends downward and lengthwise of the frame, having a branch-pipe, N, leading into the lire-box O, and having the horizontal burner tube or tubes O', and a second branch-pipe, P, extending upward under the cylinder H', and likewise provided with burner-tubes P'.

The tubes O' I", respectively, heat the boiler and roaster.

Extending out horizontally from pipe I), under the steam-chamber K, is a pipe, Q, provided with a number of burners, g, which keep the water in the said chamber'hot, or, when steam is used, prevent the steam from cond-ensin g.

The main supply-pipe M is provided with a cock, n, in its vertical branch below the tank L, and the branch pipes N I3 Q each with a similar cock, n', by means of which the oilsupply to the branches may be generally regulated, and also the individual supply thereto reduced or increased according to circumstances.

The peanuts being in cylinder H, which is spaced from the cylinder H', to which the heat is applied, the nuts are roasted by hot air and thoroughly cooked without danger of burning or carbonization, for the reason that the inner cylinder is never in direct contact with the H are kept .flame I am aware that a rotary roasting-cylinder in a stationary cylinder and separated there- 'rom by an air-space is not new, and l vdo not claim such devices broadly.

W'hat I claim as new, and desire to secure by Letters Patent, is

l. The combination, with the frame A, having the boiler and engine at one end, and a driven shaft having a fly, D, and a grooved pulley-wheel, D', operated by said engine, of a fixed casing-cylinder, H', at the other end of frame A, a concentric cylinder, H, journaled in the ends of cylinder H' and rotating there- IOO hcn

in, the pulley F, endless belt E, discharge and feed doors e b in the cylinder H, feed and discharge door c in cylinder H, fixed chute-flange d, extending across the interval between the cylinders at the bottom side of door e, and a Warming-pan, J, arranged to receive the discharge, as shown and described.

2. The combination, with a frame, A, having a boiler, B, engine C, and tire-box O at one end, the fixed cylinder H', the concentric rotating cylinder H, separated therefrom by an air-space, the fixed chute-fiange d, extending across said space, and the door e in cylinder H', of an intermediate pan, J, receiving the discharge from the :Xed chutc-ange through door e, and having the steam or Water chamber K, as shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two-witnesses.
